This may sound silly, but I assume any coolant can be used in the G37's coolant system. Are coolants that contain os silicates ok to us? My Acura TL had an Acura OEM type of coolant that did not contain os silicates since they would eat the seals on the waterpump, etc?

So, what coolant do you use in your G37? I am getting ready to do a flush...

 

I went to the dealership and bought the Nissan green coolant, since I have an 08. I had to mix it myself, but that was simple.
